Mechanisms underlying speciation in plants include detrimental (incompatible) genetic
interactions between parental alleles that incur a fitness cost in hybrids. We reported on …

Hybrid incompatibility resulting from deleterious gene combinations is thought to be an
important step toward reproductive isolation and speciation. Here, we demonstrate …

Darwin's Origin of Species is often criticized for having little to say about speciation. The
complaint focuses in particular on Darwin's supposed failure to explain the evolution of the …

Polyploidy is ubiquitous and often recursive in plant lineages, most frequently resulting in
extinction but occasionally associated with great evolutionary success. However, instead of …

Elucidation of gene regulatory networks (GRNs) underlying aspects of leaf development in
multiple model species has uncovered surprisingly plastic regulatory architecture. The …

Interspecific and intraspecific hybrid sterility is a typical and common phenomenon of
postzygotic reproductive barrier in rice. This is an indicator of speciation involved in the …

Abstract In the Bateson-Dobzhansky-Muller (BDM) model of speciation, incompatibilities
emerge from the deleterious interactions between alleles that are neutral or advantageous …

Reproductive barriers are commonly observed in both animals and plants, in which they
maintain species integrity and contribute to speciation. This report shows that a combination …

Root growth and architecture are major components of plant nutrient and water use
efficiencies and these traits are the matter of extensive genetic analysis in several crop …

Systems biology attempts to answer biological questions by integrating across diverse
genomic data sets. With the increasing ability to conduct genomics experiments, this …
